I bought a can of Rocol Ultraglide in 2005 for £10.20 & VAT & delivery, say £15 in total. I must admit that having looked at the RS website, I'm a bit shocked by the price of £20 + the extras. Fortunately at the moment, I only use it on the cross-slide and the top-slide because these do not have any other method of lubrication. It does seem to work for me.
For other lubrication I use H68 oil bought from Hallett Oils although I do know that the company has now changed hands. On my lathe there are two ball type oilers: I use a pressure type oil can, one with a small nozzle with which I push down the ball and squeeze away merrily, too merrily in fact.
I have noticed with this oil that there appears to be a permanent seepage from the oilcan. I've now tried two and have taken to keeping the oilcan in a suitable tin to hold the seepage. I then use a small brush to transfer any oil I may need. I'm not sure waht is going on, but it is almost as if this stuff is able to climb and and escape, something like water will climb up a narrow tube.
On the lathe I also have two other oil holes. The oilcan spout works in one of them, but the other, which I added, ay be a trifle too small. At anyrate, I have now taken to using a straightened out paperclip and allowing the oil to run down the wire into the hole. That way I no longer get too much in and overflowing.
The milling machine is presently in bits, and might well be for sometime yet. There is no means of lubrication on this and I was expecting to use the spray however I'm now wondering if I should perhaps add some oilers whilst I have it in bits.
